I don't recall stating that men played Mr. Mom, most likely because I didn't. lol That being said, many Native American groups (as all human societies) had male members who were two-spirits. Some of these men performed women's traditional roles, including cooking, childcare, and garment-making.
Here is an interesting article on more recent (last few centuries) hunter-gatherer society women.
Early African Women: Hunters, Warriors & Rulers
And another:
Gender roles in history: women as hunters
It is true that many primitive societies assigned rigid roles to the sexes, but many were more egalitarian and utilized members' talents in the roles they were best at.
When speaking about primitive tribes, regardless if 50 years ago or 50,000 years ago, the human variable remains the same. As previous links showed, there is a lot of evidence showing lifespans and infant/childhood mortality rates. While studying tribes 50,000 years ago can't be done directly, tribal societies over the past few hundred years have been extensively studied and can be used for comparison to what data has been found on the older societies.
AKAIK, much of the data correlates; human beings remain consistent and predictable in primitive conditions. While there will be anomalies like Amazonians, the Agojie and China's all-female army under Lin Siniang, they are the exception, not the rule.
I get the feeling that by saying "women tended the campfires", some here equate that with "a woman's place is in the kitchen". That is absolutely
not what I'm saying.
Primitive societies are closer to Marx's "From each according to his ability, to each according to his needs". A primitive tribe, besides being limited by its infant/childhood mortality rate, is also limited by the amount of food available. Less food per person means conflict and starvation. A tribe would either split to find better food sources or kill enough tribal members to be sustainable.
While men and women are equal intellectually, they do have differences in
how they think. This goes back to my point about a hunter's mindset versus a gatherer's mindset. More to the point for attractiveness; it applies to why men are more visually-oriented and non-verbal than women who tend to be more nurturing and verbal.
Men being better hunters and women being better camp-tenders is not a Zero-sum game. It's the exact opposite: it's a win-win in terms of survival. A true Yin-Yang where the sum is greater than the individual parts.
Again, modern society alters this basic formula, but if we are to better understand human beings in 2022, then it's best to try to understand how and why they survived from a few thousand or less near extinction about 70,000 years ago to become the apex predator of the planet with over 8B human beings.

We examine community longevity as a function of group size in three historical, small scale agricultural samples. Community sizes of 50, 150 and 500 are disproportionately more common than other sizes; they also have greater longevity. These values mirror the natural layerings in hunter-gatherer societies and contemporary personal networks. In addition, a religious ideology seems to play an important role in allowing larger communities to maintain greater cohesion for longer than a strictly secular ideology does. The differences in optimal community size may reflect the demands of different ecologies, economies and social contexts, but, as yet, we have no explanation as to why these numbers seem to function socially so much more effectively than other values.
